Presentation / Conference Contribution
Romero Legarreta, I., Addison, P., Grubb, N. R., Clegg, G. R., Robertson, C. E., & Watson, J. N. (2005). A comparison of continuous wavelet transform and modulus maxima analysis of characteristic ECG features. In Computers in Cardiology, 2005 (755-758).

The continuous wavelet transform (CWT) offers a valuable tool for the analysis of signals as it provides precise location in time of high frequency components. The selection of a mother wavelet with high correlation with the signal under study provid...

Secondary wavelet feature decoupling (SWFD) and its use in detecting patient respiration from the photoplethysmogram. (2003)
Presentation / Conference Contribution
Addison, P., & Watson, J. N. (2003). Secondary wavelet feature decoupling (SWFD) and its use in detecting patient respiration from the photoplethysmogram. In Proceedings of the 25th Annual International Conference of the IEEE Engineering in Medicine and

We describe a method for the identification of time-frequency features associated with patient respiration in the wavelet decomposition of the photoplethysmogram where the respiration features are masked by other signal components with similar spectr...

Modulus maxima derived from the continuous wavelet transform offers an enhanced time-frequency analysis technique for ECG signal analysis. Features within the ECG can be shown to correspond to various morphologies in the continuous modulus maxima dom... Read More about R-wave detection using continuous wavelet modulus maxima..

Journal Article
Addison, P., Watson, J. N., Clegg, G. R., Steen, P. A., & Robertson, C. E. (2002). Finding coordinated atrial activity during ventricular fibrillation using wavelet decomposition. IEEE engineering in medicine & biology magazine the quarterly magazine of the Engineering in Medicine & Biology Society, 21, 58-65. https://doi.org/10.1109/51.993194

Until recently, the ECG recorded during ventricular fibrillation was thought to represent disorganized and unstructured electrical activity of the heart. Using a new signal analysis technique based on wavelet decomposition, we have begun to reveal pr...
